UNITED STATES PATENT. OFFlCE LEO GOLDHAMMER, F MUNICH, GERMANY, ASSIGNOR TO AGFA ANSOO CORPORATION, OF BINGHAMTON, NEW YORK, A CORPORATION OF NEW YORK AUTOMATIC FOLDING CAMERA WITH SELF-ERECTING LENS CARRIER Application filed. August 1, 1928, Serial No.'296,722, and in Germany August 9, 1927.

The present invention relates to automatic the notches 13 engage the carrier 1 as shown folding cameras with self-erecting lens-carin Fig. 1. The carrier 1 is then firmly held rier, more specifically to a locking device for because of the tension on the links 7. the lens-carrier in folding cameras in which I claim: the lens-carrier together with the lens and 1.
